BARN-FRAMING MACHINE.

Application filed March 14, 1912.

To all whom it may concern:

Be it known that I, AUGUST F. WOLF, a citizen of the United States, residing at Elma, in the county of Howard and State of Iowa, have invented certain new and useful Improvements in Barn-Framing Machines, of which the following is a specification.

This invention relates to wood-working machines and has special reference to woodworking machines adapted for shaping and boring timber to be used in the construction of frames for barns and other buildings.

The invention has for its object to provide an improved wood-working machine of this kind by means of which framing timbers may be formed with tenons and the necessary sockets and holes for said timbers.

The invention further has for its object to provide an improved wood-working machine by means of which not only can framing timber be formed with tenons and the necessary sockets and holes required for timber frames, but also for forming the necessary bevels of the joints.

The invention further has for its object to provide. an improved wood-working machine for forming tenons on framing timbers, and also for cutting the same and boring the necessary holes and sockets therein.

The invention has for its further object the provision of a device by which timbers may be mounted on a frame and presented first to a machine for cutting a tenon, sec 0nd to present the timbers after the tenon has been formed to an augur for boring the timber wherever necessary, and lastly in boring pin holes in the tenon, and presenting the timber in condition for framing when it leaves the machine.

With these and other objects in view, the invention consists in an improved machine for cutting, shaping and boring framing timbers and in details of construction thereof as hereinafter set forth and claimed.

Referring to the accompanying drawings: Figure 1 is a plan view of' a wood-working machine constructed in accordance with this invention. Fig. 2 is a side view thereof. Fig. 3 is an enlarged detail plan view of a portion thereof with parts broken away looking at the underside of the machine.

sockets. Fig. 5 is an enlarged detail view in elevation, with parts broken away, and in cross section, of a portion of the machine, showing the saw mechanism and saws for forming tenons. Fig. 6 is an enlarged detail side view, partly in section, showing a pin hole auger and operating mechanism. Fig. 7 is a transverse sectional view taken on the axis of shaftlO in Fig. 1. Fig. 8 is a longitudinal sectional view taken about the mid-line of the machine, and Fig. 9 is an enlarged perspective of a fragment of the work produced.

The invention comprises in its general features an oblong frame provided with means for advancing framing timbers longitudinally thereon to the wood-working mechanism, which consists of a device embracing a number of saws for forming tenons and also the beveled portions of the joint ends of the timber; a device for operating a large, reciprocating, rotating, hollow chisel; and a pin auger mechanism.

To illustrate the manner of carrying out the invention, 1 indicates an oblong, rec tangular frame constructed in any suitable manner and preferably mounted on wheels 2, having their shafts 3 mounted in bearings 4 in said frame, whereby the machine may be transported from place to place.

Mounted on one end of the frame 1 is a mechanism for forming tenons on the ends of framing timbers, said mechanism being preferably constructed as follows, with a pair of vertical bars 5 spaced apart from each other and connected at the top by a cross bar 6, and at the bottom by a cross bar 7, having its ends secured to hangers 8, depending from the bars 5. Rotatably m0unted in each of the hangers 8 is a crank 9, having one of its arms mounted in a bearing 10 depending from the frame of the machine. Pivotally connected at one end with each of the cranks 9, is a crank lever 11, pivoted at its other end to a pin 12, mounted on the block 13 slidable in vertical grooves 14; in the adjacent bar 5. Mounted on the outside of each of the bars 5 is a bracket 15, having a vertical arm 16, to which is pivoted a manually operated hand lever 17, which in turn is pivotally connected to a rod 18, movable through a hole in the bracket 15 and adapted to engage the slots 19 in a curved frame 20, mounted on the side of the frame 1.

It will be seen from the foregoing constructionthat the frame constructed of the side bars 5 and the top and bottom bars 6 and 7, is suspended so as to swing into and out of elevated, inclined positions and held therein by the locking rods 18, engaging the curved frames 20 for a purpose hereinafter explained.

Mounted in vertical grooves 21 on the inner side of the vertical bars 5 is a vertical frame adapted to reciprocate therein and consisting of the vertical bars 22, connected together at the top and bottom by the cross bars 22,provided with notches 22", in which are located and held in adjusted, spaced relation to each other, vertical rip saws 23, secured in adjusted position by any suitable clamping means, whereby the saws may be spaced apart so as to be adjusted for any size tenon to be cut. Secured to the top and bottom of the vertical bars 22 are transverse bars 24, each provided with a groove 25, in which are slidably mounted vertical'bars 26, each having mounted on its inner side a vertical saw 27, secured at its ends to the bar 26 by a projection 28, the frame formed by the cross bars 24 and the vertical bars 26, being spaced from the supports of the saws 23 so as to locate the saws 27 at the necessarydistance from the saws 23, so as to cut off the portions sawed by the saws 23 at the necessary point for forming the desired length of a tenon. The saws 27 are laterally adjusted by means of the levers 31 and 31 so. as to cause them to cut the desired depths in the timber to form the tenon, and as here shown preferably by means of a pin 29, slidably mounted in a vertical oblong slot 30 in each of the vertical bars 26, and connected by means of the double armed levers 31 and 31, pivoted to the vertical bars 5. These levers may be operated by any suitable means for sliding the bars 26 in the grooved transverse bars 24, so as to adjust the position of the saws 27, and, as here shown, by a slot 31" in the upper end of the lever 31, engaging a pin 32, projecting from a slide bar 33 mounted on the top of the vertical bars 5, and having slots 33 engaging the pins 33" mounted on the said bars 5. The slide bar 33 may be manually operated as well as the double lever 31. r

One of the arms of the cranks 9 is formed with an extension 34, on which is loosely mounted a pulley 35, having a clutch projection 35 adapted to be engaged by a clutch 36 splined upon the extension 34 serving as a shaft for the pulley 35. The clutch 36'.is formed with an annular groove 36, which is engaged by a forked lever 37 pivotally mounted on the side of theframe 1., and serving to move the clutch 36 into and out of engagement with the clutch 35 of the pulley 35. The pulley 35 is connected by an endless band 38 with the pulley39 mounted on the shaft 40, located beneath and extendingtransversely across the frame 1, and having its bearings in said frame. Mounted on the shaft 40 is a pulley 41 connected by an endless band 42 with a pulley 43, mounted on the shaft 44 of a suitable engine or motor 45, which supplies the power for driving the operating parts of the machine.

The engine 45 is supported on an elevated frame 46 mounted on the frame 1, and permitting the passage thereunder of the timbers, which are advanced to the cutting mechanism. To enable the pieces of timber to be advanced toward the cutting mechanisms, a suitable trackis provided, which as here shown consists of longitudinal bars 47 mounted on cross bars 48 of the frame 1,

and extending beneath the frame 46andfor ward to a point, to enable the timber to be carried forward into position for being operated upon by the saws 23 and 27. Suitable means are provided for moving vthe timbers forward and back upon the rollers 49, and as here shown preferably consisting of a transverse frame 50, mounted on the bars 47 and straddling the track, so as to permit the timbers to pass under said frame, said frame being provided with a guide 51, which is suspended from a vertically movable cross bar 52,'slidable in the'slots 52 in the frame 50, and adjustable by means of a hand wheel 53 and a screw 53. V

V In order to bore holes in the timber, a boring mechanism is provided at one side of the frame adjacent to the track over which the timber is moved. The said mechanism is preferably constructed and arranged as follows, and consists ofa pair of uprights 54 mounted on one side of the frame 1, and

braced by means of diagonal supports 55. Mounted in the uprights 54 is a frame 56, which is vertically slidable therein and has a bit guiding head 57 formed at its lower 6X1 tremity. Mounted in the frame 56 is the chuck 59, in which the boring bit is fastened by a set screw 58, said chuck being provided at its ends with bushings 60. Connected with the chuck 59 is a rotary shaft 61, having its hearings in the cross bar 62, connecting the upper ends of the uprights 54. Mounted on the shaft 61 is a grooved pulley 63, having a collar 64, which is adapted to be secured to the shaft 61'by means of a pin 65, projecting into a slot 66 in the shaft 61. By means of the pin 65 and the slot 66 the shaft 61 is permitted to vertically reciprocate in conjunction with the vertically re ciprocating frame 56. Mounted at the upper end of'the upright 54, on the outside thereof, is a transverse roller 67 located in bearings 68. The shaft 61 is driven by means of a cord 69passing over the grooved pulley 63 and the roller 67, andextending downward and passing over the grooved pulley 70 on the shaft 40. Mounted on the shaft 40, outside of the frame 1, is a toothed pinion 71, which meshes with a large, toothed gear-wheel 72, mounted on a stub shaft projecting from the frame 1, and mounted on said stub shaft is a pinion 7 3, meshing with a large toothed gear wheel 7 4 mounted on one end of a shaft 75, located in the side of the frame 1, the other end of said shaft having a beveled gear wheel 76 meshing with a beveled gear wheel 77, loosely mounted on a shaft 77, and having a clutch 78, adapted to be engaged by a clutch 79 splined on the shaft 77 and provided with an annular groove 80, engaged by the forked end 81 of a lever 82, pivoted to the under side of the frame 1, and extending transversely thereto, and beneath a strap or keeper 83 at one side of the frame 1 and beyond the same. The frame 56 is vertically reciprocated by means of a pitman 8% pivoted at one end of a projection 85, extending from the frame 56, and at its other end to a disk wheel 86, mounted on a shaft 7 7 It will be seen that by means of the operating lever 82 and the slidable clutch 80, the shaft 77 may be operatively disconnected from the driving mechanism, and thereby the hollow chisel reciprocating mechanism disconnected from the driving mechanism.

Mounted on the frame 1, at one side of the track on which the timber is advanced, is a mechanism for boring pin holes, which is preferably constructed and arranged as follows: 87 indicates a frame slidably mounted on the adjacent cross bars 48, and formed with the end bearings 88, in which is rotatably mounted the frame 89 having a projection 90 at one end with a head 91, in which is secured the pin auger 92, pro jecting transversely to the track on which the timber is advanced. The projection 90 slidably engages the supporting frame 89 and is adjustable therein by means of the oblong, slotted plate 93, slidably mounted on one side of the frame 87 by means of bolts 94:, projecting through a slot 95 in the plate 93, the forward end of said plate being formed with the angular projection 96,

which engages an annular groove 97 in the head 91. The slide 93 is formed at its inner end with a lateral projection 98 which serves as a handle therefor. It will be seen that by this means the pin auger 92 may be adjusted to the desired position for boring. In order to adjustably elevate the pin auger 92 to the proper position the frame 87 is vertically adjustable by being supported on a vertically adjustable base 99, vertically adjustable by means of a screw 100, provided with a hand wheel 101. The pin auger 92 is rotated by means of a beveled wheel 102 mounted on a projection 103, extending through the bracket support 104:, and connected to the rotatable frame 89. The beveled gear wheel 102 meshes with a beveled gear wheel 103, slidably mounted on a vertical shaft 10% by means of a collar 105 having a pin 106, engaging a slot 107 in the shaft 104. The shaft 104: extends through the frame 1, and has mounted on its lower end a beveled gear wheel 108, which meshes with a beveled gear wheel 109 mounted in the frame 1, on the side of the frame as shown in Fig. 3, and secured to the shaft 40. When the frame 87 is elevated in order that the beveled gear wheel 103 shall mesh with the beveled gear wheel 102, the beveled gear wheel 103 is moved upward on the shaft 104 by loosening the pin 105, and is secured at the proper elevation to the shaft 104 by tightening said pin. It will be seen also that the pin hole auger mechanism may be disconnected from the driving mechanism by' elevating the frame 87, so as to dis engage the beveled gear wheel 102 from the beveled gear wheel 103. The frame 87 is secured in adjusted position by means of the screws 110, each having a crank handle 111.

The operation of the machine is as follows: The piece of timber to be cut is advanced on the track over the rollers 49 until one end thereof is brought to the proper position adjacent to the saws 23 and 27. As the timber is advanced forward against the saws 23, which are reciprocated by the reciprocating frame in which they are mounted, the end of the timber is cut to the necessary depth to form a tenon and the saws 27 are then adjusted by sliding them in their supports to cut off the pieces sawed out by the saws 23. The pin holes are bored in the timber by placing the latter in the proper position adjacent to the pin auger 92, which has been adjusted to the proper position by means of the adjustable frame 87 The timher is operated upon by the hollow chisel by placing the timber in the proper position beneath the same and operating the vertically reciprocating frame 56 and the rotary shaft 61. By tilting the frame formed of the uprights 5 and the cross bars 6 and 7 to the desired inclination, the saws will be brought into such a position as to cut the desired bevels on the ends of the timber.

It will be seen from the foregoing description that a woodworking machine of the character described is provided by means of which tenons may be effectively formed on the ends of timber, and the necessary holes and sockets bored out, and bevels also formed.
